Docker Community Forums

I am running a fresh install of Ubuntu Server 18.04 via Hyper-V with distinct physical network ports/distinct IP addresses for the host and VM. I believe the host, VM and virtual switch are all configured correctly, as the following all work as expected:

internet on both host and VM

network discovery and file sharing on the host (no samba on the VM to test this)

ping to both host and VM responds < 1ms from local lan

I then installed docker (bionic stable) and docker compose, and tested with the hello world container. This worked as expected.

And now, the problem… An nslookup to the VM’s IP does not respond. Also, I notice the “PORT” column returned for these services with docker ps is empty. That seems incorrect.

The 15 stars on Mr. Ewen’s repo tell me that hundreds of people are successfully using this. But I am new enough to docker that I am unsure where to start with troubleshooting. Any help would be appreciated.
